UNITED STATES JOHN HAYES, OF BELLE VER-NON, PENNSYLVANIA.

INTERNAL-COMBUSTION ENGINE.

Original application filed March 1, 1922, Serial No. 540,218. Dividedand this application filed December 27, 1923.

To all whom t may concern Be it known that I, JOHN HAYES, a citizen ofthe United States, residing at Belle Vernon, in the county of Fayetteand State of Pennsylvania, have invented certain new and usefulImprovements in Internal-Coinbustion Engines, of which the following isa specification, reference being had to the accompanying drawings.

' This invention relates to certain improvements in internal combustionengines and it is primarily an object of thel invention to provide meanswherein a make and break mechanism for the ignition system is caused tofunction as required.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved internalcombustion engine whereby certain important advantages are attained andthe device rendered simpler, less expensive and otherwise more.convenient and advantageous for use, as will be hereinafter more fullyset forth.

The novel features of my invention will hereinafter be vdefinitelyclaimed.

In order that my invention maybe the better understood, I will nowproceed to describe the same with reference to the accompanyingdrawings, wherein 1# n Figure 1 is a view in top plan of an internalcombustion engine constructed in accordance with an embodiment of myinvention;

Figure 2 is an enlarged fragmentary sectional view taken substantiallyon the line 2--2 of Figure 1;

Figure 8 is a fragmentary sectional view taken substantially on the line3-3 of Figure 1;

Figure t is an enlarged fragmentary sectional view taken substantiallyon the line 4 4 of Figure 1;

Figure 5 is a fragmentary view in side elevation of the engine as hereinset forth.

As disclosed in the accompanying drawings, A denotes an engine blockcast to provide two parallel series of vertically disposed cylinders C,the cylinders C of one series being of equal number with the cylindersin each series a multiple of two as is particularly described andillustrated in my copending application Serial No. 540,218 filed March1, 1922, of which the present application is a division.

serial No. 683,035.

H denotes a head common to theJ cylinders C of both series and which isprovided with the inlet ports 4 each of which is under control of avalve 6 having associated therewith an operating rod 8. The rod 8 isfreely disposed through the head H and the outer or extended end portionthereof is secured toan end portion of a cross member 11, each crosslmember 11 having secured thereto the rods 8 associated with the valves6 arranged in the corresponding cylinders C of both sets. Rotatablysupported by the head H and extending longitudinally thereof above themembers 11 is a cam shaft 27 provided with the cams 28 which engage thecross members 11 in proper timed sequence to effect the desired openingof the valves 6, said shaft 27 being in driven connection with the driveshaft of the motor (not shown).

Each of the members 11 has freely disposed therethrough the upstandingpins or shanks 30, each of which above the members 11 being providedwith the head or enlargement 31. Interposed between each of the members11 and head H and encircling the shanks 30 are the eXpansible members 32herein disclosed as coiled springs which operate to constantly urge thevalves 6 toward their seats. The head H has in communication with eachof the cylinders C an opening in which is arranged a spark plug 34, the`operating circuit for which is normally open. Extending longitudinallyof the head H adjacent each pair, of complementary cylinders C is a rockarm supported between a pair of upstanding lugs or bearings 36. The armhas a pair of inwardly directed arms 37 provided in their outer endswith the contact members 38.

Substantially midway its length each rock arm 35 is provided with anoutstanding lug or arm 39 with which is engaged an eXtremity of aretractable member or coiled spring 40, the opposite. end portion ofwhich is anchored, as at 411, to the head H. The retractable member orspring 40 serves to constantly rock the arm 35 in a direction tomaintain the contact members 38 in an inoperative position. By thedepression of the arms 87, the Contact members 38 are adapted to haverequisite electrical connection with spark plugs so that the desiredfiring will be had.

Transversely opposed arms 35 operate in CII llO

unison and in ra. manner to cause simultaneous firing of the plugs v34`associated with the cylinders C in which the pistons have unitary andcorresponding movement, as set forth in my copendingapplicationhereinbefore identified. In order to effect this simultaneous movementof the. arms 35 the central portions of said arms are provided with theinwardly directed lugs 42, Pivotally connected with these opposed lugsare the end portions of a cross member 43. Extending outwardly is an arm44 continued by an upstanding extension or finger 45. This finger 45 ispositioned directly below a cam 4G carried by the shaft 27 so that uponrotation of the shaft 27, he cross members 43 will be forced downwardlyin proper timed sequence to close the ignition circuits.

From the foregoing description it is thought to be obvious that aninternal combustion engine constructed in accordance with my inventionis particularly weill-v adapted for use by reason of the convenience andfacility with which it may be assembled and operated, and it will alsobe obvious that my invention is susceptible of some change andmodification without departing from the principles andspirit thereof andfor this reason I do not wish to be understood as limiting myself to theprecise arrangement and formation of the several parts herein shown incarrying out my invention in practice except as hereinafter claimed.

I claim l. In an internal combustion engine, a pair of spaced cylinders,an ignition means associated with the cylinders including a spark plugextending within each of the cylinders, the circuit for each of saidplugs having a circuit closer interposed therein and comprising astationary contact, a rock shat, a contact carried by the rock shaft forengagement Iwith the stationary contact upon movement of the rock shaftin one direction, an outstanding arm carried by the rock shaft, aretractable spring engaged with said arm for normally maintaining thecontact 'carried by the rock shaft out of engagement with the stationarycontact, each of the rock shafts being provided with an inwardlydirected arm, a member connecting the inwardly directed arms of the rockshafts, and means engaging said member for int-ermittently moving therock shafts to bring' the Contact members carried thereby intocontacting relation with the stationarv contacts :2. In an internalcombustion engine, an ignition means associated with the cylindersincluding a spark plug extending within 3. Inan internal combustionengine, a'

pair of spaced cylinders, an ignition means associated with thecylinders including a spark plug extending within each of the cylinders,the circuit for each of said plugs having a circuit closer interposedtherein and comprising a stationary contact, a rock shaft, a contactcarried by therock Ashaft for engagement with the stationary contactuponmovement of the rock shaft in one direction, means for normallymaintaining the contact carried by the rock shaft out of engagement withthe stationary contact, each of the rock'shafts being provided with aninwardly directed arm, a member connecting the inwardly directed arms ofthe rock shafts, and means engaging said member for intermittentlymoving the rock shafts to bring the contact members carried thereby intocontacting relation with the stationary contacts.

4. In an internal combustion engine, a pair of spaced cylinders, anignition means associated with the cylinders including a spark plugextending within each of the cylinders, the circuit for each of saidplugs having a circuit closer interposed therein and comprising astationary contact, a rock shaft, a contact carried by the rock shaftfor engagement with the stationary contact upon movement of the rockshaft in one direction, means for normally maintaining the contactcarried by the rock shaft out of engagement with the stationary contact,each of the rock shafts being providedwith aninwardly directed arm, almember connecting the inwardly directed arms of the rock shafts, an armcarried by the member terminating in an upstanding portion, and a drivencam contacting with said upstanding oortion to intermittently depressthe mem er to bring the contact members carried by the rock shafts intocontacting relation with the stationary contacts.

In testimony whereof I hereunto aiiix my signature.

JOHN HAYES.
